The landing take-off (LTO) cycle three-year (2016 to 2018) data were gathered from Civil Aviation Authority Nepal (CAAN) for all types aircrafts fuel consumption each ground service equipment (GSE) collected Airlines Corporation (NAC). With help LTO factors published by different institutions data, was calculated overall (international, domestic, helicopters GSE) CO₂ in year 2016, 2017 2018 found be 56.55, 65.66 71.89 Kilotonnes respectively. Upon validation discrepancy 2.59% found. forecasted up-to 2030 considering two scenarios namely, time series analysis regression analysis. Lastly, GSE scenario; Electrical Construction Aerobridge studied it that will reduced 80% if implemented.
